Mobile technology is the technology used for cellular
communication. Mobile code division multiple access (CDMA) technology has grown
rapidly over the past few years.
There are two common frequency bands that all cell phone
carriers use. The Cellular band commonly referred to as 1900 uses the
frequencies 1850-1990. The other band is PCS which is the 800 MHz band uses
frequencies in the 824-894 range.

1876. The first successful bi-directional transmission of clear speech by Bell
and Watson was made on March 10, 1876 when Bell spoke into the device, “Mr.
Watson, come here, I want to see you.” and Watson answered.

When were mobile phones first invented?
Mobile phones, particularly the smartphones that have become
our intimate companions today, are relatively new.
However, the history of mobile phones goes back to 1908 when
a US Patent was issued in Kentucky for a wireless telephone.
Mobile phones were invented as early as the 1940s when
engineers working at AT&T developed cells for mobile phone base stations.
The very first mobile phones were not really mobile phones at
all. They were two-way radios that allowed people like taxi drivers and the
emergency services to communicate.
Instead of relying on base stations with separate cells (and
the signal being passed from one cell to another), the first mobile phone
networks involved one very powerful base station covering a much wider area.
Motorola, on 3 April 1973 were first company to mass produce
the the first handheld mobile phone.
These early mobile phones are often referred to as 0G mobile
phones, or Zero Generation mobile phones. Most phones today rely on 3G or 4G
mobile technology.

The development of mobile phone technology
first mobile phones
The first mobile phone invented for practical use was by a
Motorola employee called Martin Cooper who is widely considered to be a key
player in the history of mobile phones.
Handsets that could be used in a vehicle had been developed
prior to Martin Cooper’s phone, but his was the first usable truly portable
mobile telephone.
Cooper made mobile phone history in April 1973 when he made
the first ever call on a handheld mobile phone.
Landmarks in early mobile phone history
Japan became the first country to have a city-wide commercial
cellular mobile phone network in 1979.
The Nordic Mobile Telephone (NMT) system launched in Denmark,
Norway, Sweden and Finland in 1981.
The next major step in mobile phone history was in the mid-eighties
with the First Generation (1G) fully automatic cellular networks were
introduced.
The first ever mobile phone to be approved by the FCC
(Federal Communications Commission) in the USA was the Motorola DynaTac in
1983.

the history of mobile phones
Mobile telephony developed in leaps and bounds over the next
decade, particularly with the arrival of handover technology.
This allowed users to keep their connections as they
travelled between base stations – so as a user walked from one mobile phone
mast to another, the connection and conversation would not drop or be
interrupted.
The birth of the Second Generation (2G) mobile phones was in
Finland in 1993. It was also the year that the first SMS text messages were
sent and that data services began to appear on mobile phones.
Mobiles that we use today are 3G mobiles, or Third Generation
mobiles, or even more advanced 4G handsets.
3G launched in 2001 and allowed operators to offer a huge
range of advanced services such as video calling and HSPA data transmission.
4G became commerically available in the UK in late 2012 and
offers super fast connections and similarly speedy downloads.
